Reference Radiation for Cosmic Rays in RBE Research
(2011-10-21)
When astronauts travel in space, they are exposed to high energy cosmic radiations. The cosmic ray spectrum contains very high energy particles, generally up to several GeV per nucleon. Currently NASA is funding research ...
Factors Affecting Parents' Decisions to Treat Their Children with Autism Spectrum Disorder with Complementary and Alternative Treatments
(2012-10-19)
Autism affects approximately one in 110 children in the United States. Many parents choose to treat their children with autism spectrum disorder (ASD) with complementary and alternative (CAM) treatments. In this study, ...
Ethnographic Studies of School Science and Science Communities
(2012-07-16)
In this dissertation I used the anthropological and sociocultural perspectives to examine the culture of school science and science communities. I conducted three independent studies. The first study is a meta-ethnography ...
Essays on Network Formation
(2012-10-19)
This dissertation contains two essays which examine the roles that individual incentives, competition, and information play in network formation. In the first essay, I examine a model in which two competing groups offer ...
A Comparative Study of Kalman Filter Implementations for Relative GPS Navigation
(2011-02-22)
Relative global positioning system (GPS) navigation is currently used for autonomous
rendezvous and docking of two spacecraft as well as formation
flying applications.
GPS receivers deliver measurements to
flight ...
Analog Baseband Filters and Mixed Signal Circuits for Broadband Receiver Systems
(2012-02-14)
Data transfer rates of communication systems continue to rise fueled by aggressive demand for voice, video and Internet data. Device scaling enabled by modern lithography has paved way for System-on-Chip solutions integrating ...
Gender Equity and Fertility in European Below-Replacement Fertility Countries: Poland and Estonia
(2012-02-14)
Much of the recent scholarly attention has been devoted to the low fertility situation experienced by a growing number of developed countries. In this context, the theoretical framework explicitly incorporating the issues ...
Enhanced Oil Recovery in High Salinity High Temperature Reservoir by Chemical Flooding
(2012-02-14)
Studying chemical enhanced oil recovery (EOR) in a high-temperature/high-salinity (HT/HS) reservoir will help expand the application of chemical EOR to more challenging environments. Until recently, chemical EOR was not ...
Modeling Gene Regulatory Networks from Time Series Data using Particle Filtering
(2012-10-19)
This thesis considers the problem of learning the structure of gene regulatory networks using gene expression time series data. A more realistic scenario where the state space model representing a gene network evolves ...
The Potential for Activated Biochar to Remove Waterborne Viruses from Environmental Waters
(2012-07-16)
The need for clean potable water and sustainable energy are two current and pressing issues with implications affecting the global population. Renewed interests in alternative energy have prompted researchers to investigate ...
